DISK WHEEL To all whom it may concern:

Be it known that l, GEORGE E. HARVEY, a citizen of the United States, residing at Buffalo county of Erie, State of New York have invented certain new and useful improvements in Disk Wheels; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in vehicle wheels, and particularly to those adapted for use on motor vehicles, the principal object being to provide a wheel having disks instead of spokes, in which the disks are so designed and arranged relative to each other that a structure of great strength and resiliency is had, with a minimum of weight.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish. by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Fig. 1 is a radial half-section through one form of the wheel.

Fig. 2 is a similar view of another form.

Fig. 3 is a similar View of still another modification.

Referring now more particularly to the characters of reference on the drawings, and particularly at this time to Fig. 1, the nu meral 1 denotes the hub and 2 thefiired rim of the wheel, preferably arranged to receive a demountable rim thereon.

Extending from and connected to the .outer side of the rim to the hub is a disk '3, provided intermediate these points with" a plurality of circumferential convolutions or corrugations 4-. Extending from and secured to the inner side of the rim to the hub is another disk 5, provided with similar but oppositely disposed convolutions 6, the apexes of which lie in the same transverse planes as the apexes of the convolutions 4', the corresponding pairs of such apexes abut ting against each other and being connected to each other throughout their extent or at Specification of Letters l'atent.

spaced intervals by spot welding or otherwise as shown at A.

Positioned between the disks 3 and 5 and lying thereagainst and following the contours and curvatures thereof from the hub outwardly for a certain distance are other disks 7, which, being secured to the respective disks 3 and 5 strengthen the wheel considerably around the hub where the strength is most needed.

Filler blocks 8 of wood or other material are interposed between the disks 7 and surround the hub.

Referring now to Fig. 2, disks 3 and 5 are provided in the same relative and of the same design as the disks 3 and 5. Placed outside of these disks however are additional disks 9, provided with annular or circumferential convolutions 10 arranged in opposed order to those of the disks 3" and 5 the inwardly disposed apexes of these convolutions abutting against the outwardly disposed apexes of the disks 3 and 5% and being secured thereto as before. With this type. disks corresponding to the disks 7 are dispensed with.

in the design shown in Fig. 3, disks 3 and 5 correspond in design to the disks 3 and 5, but are spaced apart throughout, bein preferably parallel. and do not touch eac other at any point.

Positioned outside these disks are plane disks 11, against which the outwardly extending apexes of the convolutions 12 of the disks 3 and 5 abut, and are connected thereto along the lines of abutment, by spotwelding or otherwise.

By means of any and. all the foregoing described methods of construction, the principle of reverse arches is employed, making, will be evident, wheels of great strength and resiliency with a minimum of weight of metal employed to gain these ends.

From the foregoing description it will be readily seen that l have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detall the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims.

Having thus described my invention what to rim, and another disk similarly extending having annular convolutions, the alternate apexes of which abut against the first named dlsk, and are rigidly secured thereto along the lines of abutment.

3. In a Wheel, a pair of disks extending from hub to rim and having oppositely disposed annular convolutions, the inwardly disposed apexes of such convolutions abut- I ting against each other and being secured together along the lines of abutment.

4. In a wheel, a pair of disks extending from hub to rim and having oppositely disposed annular convolutions, the inwardly disposed apexes of such convolutions abutting against each other and being secured together along the lines of abutment and additional disks positioned outside. the first named disks and provided with annular convolutions arranged in reverse ordento those on the first named disks and abutting thereagainst and secured thereto.

5. In a wheel, a pair'of disks extending from hub to rim and having oppositely disposed annular convolutions, the inwardly disposed apexes of such convolutions abutting against each other and being secured together alongthe lines of abutment and additional disks positioned outside the first named disks and abutting against the outwardly protruding apexes of the convolutions thereof, and being secured thereto along the lines of abutment.

In testimony whereof I affix my signature.

GEORGE E. HARVEY.
